This page shows the final groups resulting from the splits of Actinopterygii, the ray-finned fish. Smegmamorpha splits five ways. The two orders isolated by this split are Synbranchiformes and Mugiliformes. A family is also isolated by this split: Elassomatidae, the Everglades Pygmy Sunfish. The two other classifications resulting from this five-way split are Atherinomorpha and the Gasterosteiformes/Syngnathiformes group. The latter contains the two orders from which the group gets its name. Atherinomorpha contains three orders.
